The Berkey® Secret
Have you ever wondered how Berkey® water filter systems removes chlorine, heavy metals, chemicals including herbicides, pesticides, organic solvents, VOCs, detergents, cloudiness, silt, sediment, foul tastes and odors? Or, how Berkey ® systems are able to reduce heavy metals such as cadmium, chromium, copper, lead, mercury, aluminum and other unhealthy heavy metals without removing the healthful and beneficial minerals that your body needs?
The unique Berkey ® design combines the age-old process of micro-porous filtration coupled with modern state-of-the-art technology and the highest quality materials to bring you the finest water water filter system available anywhere. The media within the elements remove contaminants by a surface phenomenon known as “adsorption” which results from the molecular attraction of substances to the surface of the media. The exclusive water filter elements are also impregnated with proprietary “absorbing” media that promote IONIC “absorption” of pollutants within the micro-porous elements.
Another reason Berkey® water filter systems are so effective in removing contaminants from water is the extremely long “contact period”. Other filtration systems rely on water pressure that forces water molecules through the filter elements at 60-90 PSI. These water molecules come into contact with the filter media for a mere fraction of a second. By comparison water molecules, passing through the “Tortuous Path” structure of the Black Berkey filter elements, are drawn gently by gravity and stay in contact with the media for a long period of time. This allows the filter media to be more efficient in capturing contaminates. For example, if you were to hurl 100 steel ball bearings at a large
magnet, some would stick but most would bounce off. However, if you were to walk over and gently place the ball bearings on the magnet, most, if not all, would adhere to the magnet.
Berkey® gravity water filter systems fully utilize this principle. This advanced technology was developed, refined, and proven through years of diligent, investigative research and testing performed by water filter specialists, researchers and engineers.

Black Berkey® Filter Elements have been calculated to yield the greatest volume removal of toxic chemicals found in nature and caused by pollution from industry and agriculture.
